Reproduction - all living things have the ability to make more organisms like themselves
The island fox species that lives on the Channel Islands sparked interest after setting a record for the least genetic variation in sexually reproducing species. Low levels of genetic variation usually put a species at risk of extinction, but these foxes don't show any signs of extinction. Dr. Wayne, a geneticist at the University of California, studied the DNA of the island foxes to figure out how they've been able to survive for so long. He speculated that the foxes might not face as many challenges as other animals do or the people on the island helped the foxes survive. More about this study can be read here.
Adapts to Environment - an organism has traits that give them an advantage in their environment
To perform the job correctly, these are the following things that are needed: large ears to help dissipate excess heat, kidneys that retain water and prevent dehydration, thick, sand-colored fur to reflect sunlight, provide warmth at night, and help run faster across sand.
Grow and Develop - an organism must increase in size and change and mature as they go through the growth process.
J.S. Fairley - a scientist in the Department of Zoology at Queen's University Belfast. He examined the bodies of 488 adult foxes and 254 cubs -- collecting data on the length of their head and body, tail, hindfoot and ear, weight, appearance, and moult of the pelage. He used these observations to take note of the development changes.
